How to get a list of Extensions in WebComposition/DGS

If you are not sure if a DGS instance provides a certain extension, just have a look at the metadata of the service, e.g. http://www.restful.ws/datagridservice/meta. You will find the all the available extensions with the predicate http://www.webcomposition.net/2008″02/dgs/meta/extension (we say “has extension”). In the example below we find the SA-REST extension I have introduced yesterday.
